The role of the glomus body is to shunt ...
G (1–4): the grade of the cancer cells (i.e. they are "low grade" if they appear similar to normal cells, and "high grade" if they appear poorly differentiated) S (0–3): elevation of serum tumor markers; R (0–2): the completeness of the operation (resection-boundaries free of cancer cells or not) Pn (0–1): invasion into adjunct nerves

Hereditary leiomyomatosis and renal cell carcinoma (HLRCC) or Reed's syndrome is rare autosomal dominant disorder associated with benign smooth muscle tumors and an increased risk of renal cell carcinoma. It is characterised by multiple cutaneous leiomyomas and, in women, uterine leiomyomas. It predisposes individuals to renal cell ...
